Did I come off as rude?

I was skyping with a guy I've known for a year (online) for the fourth time. Skype froze near the end of our conversation before we could say goodbye, so he texted me and said he had a great time talking and he hopes I have a good night with a smiley face. I responded "Likewise. Alright, take care :)." I was a little mad at the time because he wouldn't shut up about his ex, but I tried to disguise it. I usually say something different than "take care" and I know some people interpret it as a kind "fuck off" but that wasn't my intention. He hasn't texted me in 3 days, which is out of his character.
